fix: disable PlaceAtMe spawning, use pre-placed proxies instead

ROOT CAUSE IDENTIFIED:
User found that pre-placed CK proxy HAS AI while spawned proxies DON'T.
This explains ALL the issues:
- Move() calls don't work without AIProcess
- No animations play (AI drives animation state)
- Movement is jerky (no character controller velocity management)
- AI goes neutral (proxy was never properly alive as NPC)

THE ISSUE:
PlaceAtMe spawned actors don't get proper AIProcess initialization.
They are shells without AI.

THE SOLUTION:
Disable PlaceAtMe spawning (kUsePlaceAtMeBackedRuntimeProxySpawn = false)
Use pre-placed proxy references from the Creation Kit instead.
These have full AI, character controllers, and can run naturally.

EXPECTED RESULT:
- ✅ Proxies have active AI
- ✅ Move() will work properly (AI + character controller)
- ✅ Smooth animations (velocity updates trigger animation graph)
- ✅ Natural NPC behavior (aggro state is maintained)
- ✅ No more jerky movement (continuous character controller)

NEXT:
The plugin will search for pre-placed proxy refs in the cell.
If none exist, needs fallback or user must place proxies in CK.
